ELECTRICALLY CONTROLLABLE DEVICE HAVING IMPROVED TRANSPORTATION OF THE ELECTRIC CHARGES OF THE ELECTROACTIVE MEDIUM
First Claim
1. An electrically controllable device having variable optical/energy properties, comprising:
- (A) a first substrate having a glass function;
(B) a first electronically conductive layer with an associated current feed;
(C) an electroactive medium comprising;
at least one electroactive organic compound, ea1+, capable of being reduced and/or of accepting electrons and cations acting as compensation charges;
at least one electroactive organic compound (ea2) capable of being oxidized and/or of ejecting electrons and cations acting as compensation charges;
at least one of said electroactive organic compounds (ea1+ and ea2) being electrochromic in order to obtain a color contrast; and
ionic charges capable of allowing, under the action of an electric current, oxidation and reduction reactions of said electroactive organic compounds (ea1+ and ea2), which reactions are necessary in order to obtain the color contrast;
(D) a second electronically conductive layer with an associated current feed; and
(E) a second substrate having a glass function,wherein each current feed comprises a continuous conductive strip applied to the electronically conductive layer associated with it,wherein the conductive strip is positioned over an entire perimeter or substantially over the entire perimeter of the first or second electronically conductive layer so as to strengthen the conductivity of the first or second electronically conductive layer,wherein the conductive strip is connected to an electrical power supply via one of its ends, andwherein the two continuous conductive strips are placed with an offset relative to one another.

Abstract
This device comprises the following stack of layers: a first substrate having a glass function (V1); a first electronically conductive layer (TCC1) with an associated current feed; an electroactive system (EA); a second electronically conductive layer (TCC2) with an associated current feed; and a second substrate having a glass function (V2). Each current feed is constituted by a continuous conductive strip (1-1a; 2-2a) applied to the associated electronically conductive layer, said conductive strip being positioned over the entire perimeter or substantially over the entire perimeter of said layer (TCC1; TCC2) so as to strengthen the conductivity thereof and being connected to the electrical power supply via one of its ends.
